How to Unblock a Shower Drain Without Chemicals

Posted by Sydney Blocked Drains Plumbers on 19 Oct 2025

If you’ve ever stepped into a shower only to realize that the water hasn’t been draining, you know how frustrating it can be. Not only does it slow down your morning routine, it could also make it more difficult to clean when you’re done. While chemical drain cleaners are occasionally effective, they can also damage your pipes and damage the environment. The good news is that there are plenty of ways that you can unblock the shower drain, without the need for harmful chemical solutions.

Key Takeaways

  • Chemical drain cleaners can harm pipes and the environment.
  • There are natural ways to clear a shower drain like vinegar and baking soda as well as a wire hanger or a dry/wet vacuum.
  • Use the method of baking soda and vinegar: collect items, clean the drain cover and other garbage, pour in baking soda followed by vinegar. Wait for 30 minutes then flush with boiling water.
  • For wire hanger methods Straighten the wire hanger leaving one end in its original form and then create a hook on the end and insert it into the drain to catch hair and other debris out.
  • Method for wet/dry vacuums select the "wet" mode Cover drains that overflow by a cloth or tape, connect the hose to create an airtight seal, then turn to the mode for 3 minutes.
  • Avoid future blockages by using a hair strainer in your shower, and running hot water after each usage and avoiding running grease down your drains.

Method 1: Baking Soda and Vinegar

Step 1: Gather Your Equipment

To begin you can gather the following items:

  • Baking soda
  • White vinegar
  • Boiling water
  • Rubber gloves (optional)
  • A rag or cloth

Step 2: Prepare the Drain

Remove the shower drain cover as much as you can and use tiny brushes or a toothbrush to get rid of any hair or other debris the drain’s edges. Make sure you wear rubber gloves in the event of need.

Step 3: Pour in Baking Soda in addition to Vinegar

Put one cup baking soda in the sink, followed by one cup white vinegar. Make sure to cover the drain immediately with a cloth or a towel to ensure that the reaction doesn’t explode beyond control!

Step 4: Wait

It should take about 30 minutes while the mixture works its magic. It should sound like there is a fizz and bubbling. This means it’s working!

Step 5: Rinse with Boiling Water

Remove the cover carefully and flush it with boiling water. This should clear any remaining debris and ensure that your water is flowing without a hitch.

Method 2: Wire Hanger

Sometimes all you require is a trusty wire hanger:

Step 1 Straighten It Out

Straighten out a wire hanger to the greatest extent as you can while leaving the other end in its original shape.

Step 2: Design an Hook

Make a small hook at the top of the wire you just straightened.

Step 3: Go fishing for Hair and Debris

Hook it into the drain and look to look for hairs and debris. Get rid of anything that comes up.

Method 3: Dry Vacuum Wet

If you have access to an upright vacuum that is dry and wet it could be the best option for you.

Step 1. Set the Vacuum

Set the vacuum to "liquids" (or "wet" mode.

Step 2: Cover Drainage

Cover any overflow drains with duct tape or a wet cloth to ensure maximum suction power.

Step 3: Connect Hose to Drain

Attach the hose onto your drain, creating an airtight seal.

Step 4: Turn on Vacuum

Turn on the vacuum and let it run for approximately three minutes. This should remove any obstructions from the drain of your shower.
